Sociodemographic and patient reported outcomes by racial and ethnicity status among participants in a randomized controlled trial for methamphetamine use disorder.

Background: There has been a significant increase in methamphetamine use and methamphetamine use disorder (Meth UD) in the United States, with evolving racial and ethnic differences. Objectives: This secondary analysis explored racial and ethnic differences in baseline sociodemographic and clinical characteristics as well as treatment effects on a measure of substance use recovery, depression symptoms, and methamphetamine craving among participants in a pharmacotherapy trial for Meth UD. Methods: The ADAPT-2 trial (ClinicalTrials.gov number, NCT03078075; N=403; 69% male) was a multisite, 12-week randomized, double-blind, trial that employed a two-stage sequential parallel design to evaluate the efficacy of combination naltrexone (NTX) and oral bupropion (BUP) vs. placebo for Meth UD. Treatment effect was calculated as the weighted mean change in outcomes in the NTX-BUP minus placebo group across the two stages of treatment. Results: Of the 403 participants in the ADAPT-2 trial, the majority (65%) reported non-Hispanic White, while 14%, 11% and 10% reported Hispanic, non-Hispanic Black, and non-Hispanic other racial and ethnic categories respectively. At baseline non-Hispanic Black participants reported less severe indicators of methamphetamine use than non-Hispanic White. Treatment effects for recovery, depression symptoms and methamphetamine cravings did not significantly differ by race and ethnicity. Conclusions: Although we found racial and ethnic differences at baseline, our findings did not show racial and ethnic differences in treatment effects of NTX-BUP on recovery, depression symptoms and methamphetamine cravings. However, our findings also highlight the need to expand representation of racial and ethnic minority groups in future trials.

Participant experiences in a pilot study for methamphetamine withdrawal treatment: Implications for retention.

INTRODUCTION: There is little knowledge of the perspectives of people who use methamphetamine and have participated in clinical trials, and none for interventions not intended to address abstinence. A better understanding of these experiences could lead to more patient centred clinical trial design. This study seeks to understand the experiences of people who completed a clinical trial of lisdexamfetamine for the treatment of acute methamphetamine withdrawal. METHODS: Thematic analysis of open-ended, semi-structured interviews with eight people who participated in an inpatient clinical trial of lisdexamfetamine for acute methamphetamine withdrawal. Interviews were conducted between days 3 and 6 of admission to an inner-city Sydney hospital. RESULTS: Participants described how research procedures, the research setting, and the investigational product affected their experiences while enrolled in a clinical trial. Of particular importance to participants were transparent and low burden trial procedures, a welcoming trial environment, trusting relationships and effective communication, which were linked with the participants' subsequent decision to remain enrolled in the trial. DISCUSSION: The experiences of participants in this clinical trial can be distilled into four meta-themes: agency, caring-trust, safety, and communication. Participants spontaneously linked these experiences with a capacity to remain enrolled in the study. By considering the experiences of trial participants in clinical trial design, researchers can improve the experiences of future trial participants and facilitate their choice to remain enrolled in clinical trials.

Nativity and the risk of opioid use disorder among Hispanic/Latinx women in primary care in Los Angeles, CA.

BACKGROUND: While rates of opioid use disorder (OUD) are lower among women compared to men, nativity may have disproportionate impacts on OUD risk among Hispanic/Latinx women but remain understudied. OBJECTIVE: To assess the association between country of birth and reported OUD risk among low-income Hispanic/Latinx women in primary care in Los Angeles, CA. METHODS: This was a cross-sectional study of 1189 non-pregnant, Hispanic/Latinx women attending two federally qualified health centers in Los Angeles between March and July 2013. OUD risk was assessed using the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), and moderate-to-high risk was defined as ASSIST score ≥ 4. RESULTS: Overall, 4.2% of women (n = 49) were at moderate-to-high risk for OUD. Risk for OUD was higher among US-born women compared to foreign-born women (6.7 vs. 1.7%; p < .01), those who reported 2+ chronic medical conditions (p < .01), and those who were at moderate-to-high risk for other substance use disorders (p < .01). In multivariable logistic regression analyses, being U.S.-born was independently associated with being at moderate-to-high risk for OUD among Hispanic/Latinx women as compared to those who were foreign-born (AOR = 2.8; 95% CI 1.2-6.8). CONCLUSION: Among low-income Hispanic/Latinx women presenting to primary care, one in twenty patients is at-risk for OUD. The odds of moderate-high risk of OUD were three times as high in US-born compared to foreign-born women, and higher among those with chronic medical conditions and those at risk of other substance use disorders. Gender-specific and culturally-tailored screening for OUD may inform overdose prevention interventions for US-born Hispanic/Latinx women.

Substance Use and Associated Experiences of Intimate Partner Violence Among MSM in Los Angeles, California.

This study examined the prevalence and correlates of intimate partner violence (IPV) among a cohort of racial/ethnically diverse men who have sex with men (MSM) in Los Angeles. An ongoing longitudinal cohort study of MSM in Los Angeles, constructed by design so half of the participants use substances (SU) and half are persons living with HIV, provided data. Data collection occured between 2014 and 2020. At semiannual study visits, participants completed a computer-assisted self-interview which included questions on substance use (past 6 months) and experiences of IPV (past 12 months). The criterion variable was reported physical and sexual IPV. Multivariable models generalized estimating equations (GEE) estimated associations between reported SU and physical and sexual IPV, adjusting for repeated measurement and confounders. In total, 557 persons (2,962 visits) contributed to the analysis; the median baseline age was 30 years (interquartile range: 28.0-39.0). The prevalence of IPV in the past 12 months was 22.3%, with 18.3% reporting physical and 10.2% reporting sexual IPV across study visits. Stimulant use prevalence was higher among those who reported IPV compared to those who did not (68% vs. 42.1%; p < .001); cannabis use prevalence was lower among those reporting IPV (42.3% vs. 49% respectively; p < .001). Adjusted analysis showed reported stimulant use associated with greater odds of physical IPV (adjusted odds ratio [aOR] = 2.0; 95% confidence interval [CI] [1.4, 2.8], p < .001) but not sexual IPV (aOR = 1.3; 95% CI [0.8, 2.0], p = .332). Models stratified by HIV status yielded similar results. Findings showed a high prevalence of past-year IPV experiences among MSM in Los Angeles. Findings highlight links between SU and IPV and underscore a significantly increased likelihood of IPV for MSM in Los Angeles who report current methamphetamine use. This study provides evidence to support universal IPV screening and to make available safety resources at all points where MSM seek healthcare.

Brief Report: Substance Use Care Continuum in Women With and Without HIV in the Southern United States.

BACKGROUND: Substance use (SU) contributes to poor outcomes among persons living with HIV. Women living with HIV (WWH) in the United States are disproportionately affected in the South, and examining SU patterns, treatment, and HIV outcomes in this population is integral to addressing HIV and SU disparities. METHODS: WWH and comparable women without HIV (WWOH) who enrolled 2013-2015 in the Women's Interagency HIV Study Southern sites (Atlanta, Birmingham/Jackson, Chapel Hill, and Miami) and reported SU (self-reported nonmedical use of drugs) in the past year were included. SU and treatment were described annually from enrollment to the end of follow-up. HIV outcomes were compared by SU treatment engagement. RESULTS: At enrollment, among 840 women (608 WWH, 232 WWOH), 18% (n = 155) reported SU in the past year (16% WWH, 24% WWOH); 25% (n = 38) of whom reported SU treatment. Over time, 30%, 21%, and 18% reported SU treatment at 1, 2, and 3 years, respectively, which did not significantly differ by HIV status. Retention in HIV care did not differ by SU treatment. Viral suppression was significantly higher in women who reported SU treatment only at enrollment ( P = 0.03). CONCLUSIONS: We identified a substantial gap in SU treatment engagement, with only a quarter reporting treatment utilization, which persisted over time. SU treatment engagement was associated with viral suppression at enrollment but not at other time points or with retention in HIV care. These findings can identify gaps and guide future strategies for integrating HIV and SU care for WWH.

HIV Prevention and Care Among Black Cisgender Sexual Minority Men and Transgender Women: Protocol for an HIV Status-Neutral Cohort Study Using an Observational-Implementation Hybrid Approach.

BACKGROUND: Black cisgender gay, bisexual, and other sexual minority men (SMM) and transgender women (TW) continue to be heavily affected by HIV. Further research is needed to better understand HIV prevention and care outcomes in this population. In particular, there is a need for research examining the impact of substance use and sleep health on HIV prevention and treatment outcomes among Black SMM and TW. OBJECTIVE: This paper outlines the study methods being used in the recently launched follow-up study to the Neighborhoods and Networks (N2) study, which we refer to as N2 Part 2 (N2P2). N2P2 aims to address this gap in the literature, build off the findings of the original N2 study, and identify socioenvironmental determinants of health, including whether neighborhood and network factors mediate and moderate these relationships. METHODS: Building on the N2 cohort study in Chicago from 2018 to 2022, N2P2 used a prospective longitudinal cohort design and an observational-implementation hybrid approach. With sustained high levels of community engagement, we aim to recruit a new sample of 600 Black SMM and TW participants residing in the Chicago metropolitan statistical area. Participants are asked to participate in 3 study visits across an 18-month study period (1 visit every 9 months). Four different forms of data are collected per wave: (1) an in-person survey, (2) biological specimen collection, (3) a daily remote ecological momentary assessment for 14 days after each study visit, and (4) data from electronic health records. These forms of data collection continue to assess neighborhood and network factors and specifically explore substance use, sleep, immune function, obesity, and the implementation of potential interventions that address relevant constructs (eg, alcohol use and pre-exposure prophylaxis adherence). RESULTS: The N2P2 study was funded in August 2021 by the National Institute of Drug Abuse (R01DA054553 and R21DA053156) and National Heart, Lung, and Blood Institute (R01HL160325). This study was launched in November 2022. Recruitment and enrollment for the first wave of data collection are currently ongoing. CONCLUSIONS: The N2P2 study is applying innovative methods to comprehensively explore the impacts of substance use and sleep health on HIV-related outcomes among an HIV status-neutral cohort of Black SMM and TW in Chicago. This study is applying an observational-implementation hybrid design to help us achieve findings that support rapid translation, a critical priority among populations such as Black SMM and TW that experience long-standing inequities with regard to HIV and other health-related outcomes. N2P2 will directly build off the findings that have resulted from the original N2 study among Black SMM and TW in Chicago. These findings provide a better understanding of multilevel (eg, individual, network, and neighborhood) factors that contribute to HIV-related outcomes and viral suppression among Black SMM and TW.

Loneliness and Frailty Among Middle-Aged and Aging Sexual Minority Men Living With or Without HIV: A Longitudinal Cross-Lagged Panel Analysis.

Background and Objectives: Loneliness is associated with frailty among older adults (60+), and there is evidence suggesting that this association may be bidirectional. However, there is limited evidence of this relationship over time among middle-aged and aging sexual minority men. We explored the bidirectional relationship between loneliness and frailty over 2 years among sexual minority men living with or without human immunodeficiency virus (HIV) from the Healthy Aging substudy of the Multicenter AIDS Cohort Study. Research Design and Methods: We used data from 1 118 men (561 living with HIV; 557 living without HIV) aged 40 years or older with measurement of frailty or loneliness at Times 1 (September 2016 to March 2017) and 2 (September 2018 to March 2019). Descriptive statistics were generated. We used autoregressive cross-lagged panel analysis to examine the bidirectional association between frailty and loneliness at both time points while adjusting for time-stable and time-dependent covariates at Time 1. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were generated. Results: The estimated prevalence of loneliness at both time points was 35.5%. The estimated prevalence of frailty at Times 1 and 2 were 7.8% and 12.1%, respectively. Participants reporting loneliness at Time 1 had greater odds of being frail at Time 2 (aOR = 2.14; 95% CI: 1.23-3.73). Frailty at Time 1 was not associated with loneliness at Time 2 (aOR = 1.00; 95% CI: .44-2.25). The autoregressive effects of frailty (aOR = 23.43; 95% CI: 11.94-46) and loneliness (aOR = 13.94; 95% CI: 9.42-20.61) were large. Discussion and Implications: Men who felt lonely had higher odds of being frail 2 years later while the reciprocal association was not shown. This suggests that loneliness preceded frailty and not the other way around. Early and frequent assessments of loneliness may present opportunities for interventions that minimize the risk of frailty among sexual minority men living with and without HIV.

Using ADAPT-ITT framework to tailor evidence-based interventions for addressing methamphetamine use among methadone patients in Vietnam.

INTRODUCTION: Methamphetamine use threatens positive treatment outcomes in substance use and HIV, for people with opioid use disorders (POUD) in many countries. This paper describes the adaptation of four evidence-based interventions (EBI) (motivational interviewing, contingency management, Matrix group model and SMS text messaging) for treating methamphetamine use among POUD receiving methadone maintenance therapy in Vietnam. METHODS: Following the ADAPT-ITT (Assessment-Decision-Administration-Production-Topical experts-Training-Testing) framework, we conducted 16 focus group discussions with POUD (n = 25) and providers (n = 22) at four methadone clinics in two largest cities (Hanoi in the North, Ho Chi Minh City in the South) to assess patterns of methamphetamine use and to get feedback on proposed EBIs. The proposed EBIs were properly adapted and used to train providers in two of the four methadone clinics. The revised EBIs were tested over 12 weeks among 42 POUD on methadone who use methamphetamine. Post-intervention feedback served to fine-tune the revised EBIs. RESULTS: Insights about patterns of methamphetamine use suggested that EBIs should focus on different triggers to methamphetamine use among POUD receiving methadone treatment in the two cities. All EBIs should emphasise family-related topics to build a strong motivation for treatment. Participants suggested when, where and how each EBI should be delivered. Most participants were satisfied with the adapted EBIs. Limited human resources at methadone clinics might hinder implementation of the adapted EBIs. DISCUSSION AND CONCLUSIONS: We successfully completed the adaptation of EBIs for POUD who use methamphetamine on methadone in Vietnam. The pilot testing of the adapted EBIs demonstrated feasibility and acceptability. TRIAL REGISTRATION: NCT04706624. Registered 13 January 2021. https://clinicaltrials.gov/ct2/show/NCT04706624.

A Qualitative Study of Perceptions and Preferences Regarding Social and Behavioral Risk Screening Among Primary Care Patients.

BACKGROUND: Despite its relevance for healthcare settings, social and behavioral risk screening is not systematically performed by clinicians or healthcare systems. OBJECTIVE: To address clinician concerns, such as social and behavioral risk screening disrupting the clinician-patient relationship and lack of resources to respond, we interviewed primary care patients at an academic medical center regarding their perceptions and preferences on social and behavioral risk screening. PARTICIPANTS: Between September and December 2020, we recruited a convenience sample of 14 English-speaking primary care patients 18 years + from three clinics affiliated with an academic medical center. APPROACH: Using a semi-structured interview guide, we asked about the importance of social and behavioral risk screening, whether or not and how to share social and behavioral risk factors, and how social and behavioral risk factors are addressed. We used a multi-step analytic process to identify the range and commonality of participants' responses thematically. KEY RESULTS: Participants recognized that social and behavioral risk factor domains were relevant to primary care and important for treating the patient as a whole person. Participants preferred a conversation regarding social and behavioral risk factor with their primary care providers (PCPs), and suggested that, if surveys are used, they be followed with an open-ended, in-person discussion. Participants also suggested framing the discussion as something that is done routinely with all patients so that patients do not feel judged. Participants felt comfortable sharing social and behavioral risk factors when they trusted their PCPs, and felt that discussing social and behavioral risk factors with their PCPs built trust. Participants recognized that resources exist outside of the clinic, and suggested that PCPs distribute lists of relevant community resources to patients. CONCLUSION: In our study of primary care patients on perceptions and preferences about screening and addressing social and behavioral risk factors, we found that patients were willing to share social and behavioral risk factors with their PCP, preferred an in-person discussions with or without a survey, and wanted a list of community resources to address their needs.

Substance use and other factors associated with COVID-19 vaccine uptake among people at risk for or living with HIV: Findings from the C3PNO consortium.

Objective: We describe the prevalence of COVID-19 vaccine uptake, substance use, and other factors associated with vaccine hesitancy among participants from nine North American cohort studies following a diverse group of individuals at risk for or living with HIV. Methods: Between May 2021 and January 2022, participants completed a survey related to COVID-19 vaccination. Participants included those with and without substance use. Those responding as 'no' or 'undecided' to the question "Do you plan on getting the COVID-19 vaccine?" were categorized as vaccine hesitant. Differences between groups were evaluated using chi-square methods and multivariable log-binomial models were used to calculate prevalence ratios (PR) of COVID-19 vaccine hesitancy with separate models for each substance. Results: Among 1,696 participants, COVID-19 vaccination was deferred or declined by 16%. Vaccine hesitant participants were younger, with a greater proportion unstably housed (14.8% vs. 10.0%; p = 0.02), and not living with HIV (48.% vs. 36.6%; p <.01). Vaccine hesitant participants were also more likely to report cannabis (50.0% vs. 42.4%; p = 0.03), methamphetamine (14.0% vs. 8.2%; p <.01), or fentanyl use (5.5% vs. 2.8%; p = 0.03). Based on multivariable analyses methamphetamine or fentanyl use remained associated with COVID-19 vaccine hesitancy (Adjusted PR = 1.4; 95% CI 1.1-1.9 and Adjusted PR = 1.6; 95% CI 1.0-2.6, respectively). Conclusion: As new COVID-19 vaccines and booster schedules become necessary, people who use drugs (PWUD) may remain vaccine hesitant. Strategies to engage hesitant populations such as PWUD will need to be tailored to include special types of outreach such as integration with substance use programs such as safe injection sites or recovery programs.

Intersections between syndemic conditions and stages along the continuum of overdose risk among women who inject drugs in Mexicali, Mexico.

BACKGROUND: Research on women who inject drugs is scarce in low- and middle-income countries. Women experience unique harms such as sexism and sexual violence which translate into negative health outcomes. The present work aims to provide insight into the experiences of women who inject drugs at the US-Mexico border to identify social and health-related risk factors for overdose to guide harm reduction interventions across the Global South. METHODS: We recruited 25 women ≥ 18 years of age accessing harm reduction and sexual health services at a non-governmental harm reduction organization, "Verter", in Mexicali, Mexico. We employed purposeful sampling to recruit women who inject drugs who met eligibility criteria. We collected quantitative survey data and in-depth interview data. Analyses of both data sources involved the examination of descriptive statistics and thematic analysis, respectively, and were guided by the syndemic and continuum of overdose risk frameworks. RESULTS: Survey data demonstrated reports of initiating injection drug use at a young age, experiencing homelessness, engaging in sex work, being rejected by family members, experiencing physical violence, injecting in public spaces, and experiencing repeated overdose events. Interview data provided evidence of stigma and discrimination toward women, a lack of safe spaces and support systems, risk of overdose-related harms, sexual violence, and the overall need for harm reduction services. CONCLUSION: Women who inject drugs in Mexicali describe experiences of violence, overdose, and public injecting. Women are particularly vulnerable in the Mexicali context, as this area faces a noticeable lack of health and social services. Evidenced-based harm reduction strategies such as safe consumption sites and overdose prevention strategies (e.g., naloxone distribution and training) may benefit this population. Evidence from local organizations could help close the gap in service provision in low-resource settings like Mexico, where government action is almost nonexistent.

Psychometric properties of the Treatment Effectiveness Assessment in methamphetamine use disorder.

INTRODUCTION: The ability for people living with stimulant use disorder to live meaningful lives requires not only abstinence from addictive substances, but also healthy engagement with their community, lifestyle practices, and overall health. The Treatment Effectiveness Assessment (TEA) assesses components of recovery consisting of four functional domains: substance use, health, lifestyle, and community. This secondary data analysis of 403 participants with severe methamphetamine use disorder tested the reliability and validity of the TEA. METHODS: Participants were enrolled in the Accelerated Development of Additive Pharmacotherapy Treatment (ADAPT-2) for methamphetamine use disorder. The study used total TEA and domain scores at baseline to assess factor structure and internal consistency, as well as construct validity related to substance cravings (visual analog scale [VAS]), quality of life (quality-of-life assessment [QoL]), mental health (Patient Health Questionnaire-9 [PHQ-9], Concise Health Risk Tracking Scale Self-Report [CHRT-SR16]), and social support (CHRT-SR16). RESULTS: Individual TEA items showed moderate to large correlations with each other (r = 0.27-0.51; p < .001), and strong correlations to the total score (r = 0.69-0.78; p < .001). Internal consistency was strong (coefficient α = 0.73 [0.68-0.77]; coefficient ω = 0.73 [0.69-0.78]). Construct validity was acceptable, with the strongest correlation between the TEA Health item and the general health status item on the QoL (r = 0.53, p < .001). CONCLUSIONS: TEA has acceptable levels of reliability and validity supporting prior similar findings in a sample of participants with moderate to severe methamphetamine use disorder. Results from this study provide support for its use in assessing clinically meaningful changes beyond simply reduced substance use.

Age-specific disparities in fatal drug overdoses highest among older black adults and American Indian/Alaska native individuals of all ages in the United States, 2015-2020.

INTRODUCTION: Increasing disparities within and between racial/ethnic groups in overdose deaths underscore the need to identify drivers and patterns to optimize overdose prevention strategies. We assess age-specific mortality rates (ASMR) in drug overdose deaths by race/ethnicity in 2015-2019 and 2020. METHODS: Data were from the CDC Wonder, and included information for N = 411,451 deceased individuals in the United States (2015-2020) with a drug overdose-attributed cause of death (ICD-10 codes: X40-X44, X60-X64, X85, Y10-Y14). We compiled overdose death counts by age, race/ethnicity, and population estimates to derive ASMRs, mortality rate ratios (MRR), and cohort effects. RESULTS: The ASMRs for Non-Hispanic Black adults (2015-2019) followed a different pattern than other racial/ethnic groups-low ASMRs among young individuals and peaking between 55-64 years-a pattern exacerbated in 2020. Younger Non-Hispanic Black individuals had lower MRRs than young Non-Hispanic White individuals, yet, older Non-Hispanic Black adults had much higher MRRs than older Non-Hispanic White adults (45-54yrs:126%, 55-64yrs:197%; 65-74yrs:314%; 75-84:148%) in 2020. American Indian/Alaska Native adults had higher MRRs than Non-Hispanic White adults in death counts compiled from pre-pandemic years (2015-2019); however, MRRs increased in 2020 (15-24yrs:134%, 25-34yrs:132%, 35-44yrs:124%, 45-54yrs:134%, 55-64yrs:118%). Cohort analyses suggested a bimodal distribution of increasing fatal overdose rates among Non-Hispanic Black individuals aged 15-24 and 65-74. CONCLUSIONS AND RELEVANCE: Overdose fatalities unprecedently impact older Non-Hispanic Black adults and American Indian/Alaska Native populations of all ages, deviating from the pattern found for Non-Hispanic White individuals. Findings highlight the need for targeted naloxone and low-threshold buprenorphine programs to reduce racial disparities.

Examining the Role of Autonomy Support, Goal Setting, and Care Coordination Quality on HIV PrEP Adherence in Black Men Who Have Sex with Men: HPTN 073.

Autonomy support is a concept that is derived from self-determination theory. Autonomy refers to the freedom to act as one chooses. The current study aimed to examine if autonomy support was associated with dried blood spot validated pre-exposure prophylaxis (PrEP) adherence, and whether the association was mediated by PrEP adherence goal setting and progress toward PrEP adherence goals. Our sample was drawn from Black men who have sex with men (MSM) from across three cities (Chapel Hill, NC; Los Angeles, CA; and Washington, DC) in the United States between February 2013 and September 2014. We used logistic regression to evaluate associations between study variables and path analysis to test mediation effects. Participants were, on average, 28 [standard deviation (SD) = 1.12] years old and 25% were unemployed. We found that MSM who experienced high autonomy support were more likely to adhere to PrEP [odds ratio (OR) = 1.17; 95% confidence interval: 1.00-1.38]. MSM who set PrEP adherence goals were more likely to adhere to PrEP. Moreover, MSM who reported making progress toward their goals were also more likely to adhere to PrEP. Finally, client perception of coordination quality enhanced the magnitude of the association between goal setting and goal progress and the effect size of goal progress on PrEP adherence. Autonomy support, goal setting, goal monitoring/evaluation, and care coordination quality influenced PrEP adherence among Black MSM. Our findings indicate that while it is important to set goals for PrEP adherence, goal setting may need to be accompanied by progress monitoring to achieve the maximal effect.

Brief Report: Impact of Methamphetamine Use and Rectal STIs on Systemic and Rectal Mucosal Inflammation.

BACKGROUND: Methamphetamine (MA) use is associated with sexual risk behavior as well as systemic and mucosal inflammation, suggesting parallel biological and behavioral mechanisms of HIV transmission among men who have sex with men (MSM) who use MA. Data evaluating the combined biological effects of MA use with concomitant rectal gonococcal and/or chlamydial (GC/CT) infection on inflammation are limited. SETTING: Secondary analysis of stored rectal and plasma specimens from 100 MSM participating in an NIDA-funded longitudinal cohort in Los Angeles, CA. METHODS: This cross-sectional analysis evaluated systemic and rectal inflammatory markers under 2 conditions: (1) recent MA use (by urine drug screen) and (2) rectal GC/CT infection. We evaluated 50 participants with recent MA use (25 with and 25 without rectal GC/CT) and 50 MSM without MA use (25 with and 25 without rectal GC/CT). Log-transformed plasma and rectal immune markers were regressed on MA exposure and rectal GC/CT, controlling for HIV status and age. RESULTS: Median age was 32 (range 19-45) years, and 58% of participants were living with HIV. Plasma tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8, IL-1ß, and rectal IL-6 were associated with rectal GC/CT and MA use, independent of HIV status. Higher levels of rectal TNF-α, IL-1ß, and IL-17a were associated with rectal GC/CT. CONCLUSIONS: Systemic and rectal inflammation was positively associated with rectal GC/CT and MA use. Condomless sex in the setting of GC/CT- and MA-induced immune activation may provide a basis for synergistic biobehavioral mechanisms that promote HIV/STI transmission among MSM who use MA.

Changes in Substance Use and Sexual Behaviors After a Sexually Transmitted Infection Diagnosis Among a Cohort of Men Who Have Sex With Men in Los Angeles, CA.

Sexually transmitted infections (STIs), STI reinfection, human immunodeficiency virus (HIV) acquisition, and changes in behaviors after an STI were examined in a cohort of men who have sex with men (MSM) in Los Angeles, CA. Data from a longitudinal study of MSM enrolled from 2014 with at least 1 follow-up visit through March 2020 were analyzed (n = 447; 1854 visits). Study visits every 6 months included self-interviews for sexual behaviors, substance use, and specimen collection for chlamydia, gonorrhea, syphilis, and HIV testing. Changes in behaviors were assessed using the McNemar test, and participants not diagnosed with an STI served as controls for a difference-in-difference (DiD) analysis of changes over time. Cumulative incidence of an STI was 55% (248 of 447). At 24 months after STI diagnosis, methamphetamine use declined from 50% to 35% ( P < 0.01), and median number of sex partners declined from 5 (interquartile range, 2­11) to 2 (interquartile range, 1­6; P < 0.01). Among participants at risk for HIV and diagnosed with an STI (n = 102), postexposure prophylaxis use was 35% and HIV seroconversion was 6%. Based on DiD analyses, participants diagnosed with an STI had higher levels of substance and a higher number of sex partners when compared with those with no STIs; however, declines in these behaviors were comparable to participants not diagnosed with an STI ( PDID > 0.05). Despite behavior modifications after an STI diagnosis, STI/HIV incidence was high, suggesting that MSM with STIs occupy sexual networks where reductions in sexual and substance using behaviors do not protect them from ongoing exposure to STIs and HIV.

Relating 'to her Human Side': a Grounded Theory analysis of cosmetologists' and aestheticians' relationships with clients in Black American beauty salons to inform sexual health interventions.

Due to the elevated incidence of HIV among Black American women, effective sexual health interventions are needed. To explore beauty salons as settings for such interventions, we examined Black American women stylists' experiences discussing sex-related topics with Black American women clients. Constructivist Grounded Theory methodology guided data collection and analysis. Individual intensive interviews were conducted in 2019 with 16 Black women cosmetologists and/or aestheticians who served Black women in Southern California. Analyses generated grounded theory which we refer to as Relating 'to her Human Side': Black American cosmetologist-client relationship building model. The model highlights the importance of three sets of practices: 1) playing different roles to appeal to clients' varying wants and needs, 2) creating a comfortable atmosphere, and 3) establishing a judgement-free zone. Stylists put clients at ease and consequently, clients shared stories regarding sex and relationships freely. Stylists' actions built trusting relationships with clients, thus crafting beauty salons as atmospheres favourable for sex-related conversations and potential sexual health interventions.

Lisdexamfetamine for the treatment of acute methamphetamine withdrawal: A pilot feasibility and safety trial.

BACKGROUND: There is no effective treatment for methamphetamine withdrawal. This study aimed to determine the feasibility and safety of a tapering dose of lisdexamfetamine for the treatment of acute methamphetamine (MA) withdrawal. METHODS: Open-label, single-arm pilot study, in an inpatient drug and alcohol withdrawal unit assessing a tapering dose of oral lisdexamfetamine dimesylate commencing at 250 mg once daily, reducing by 50 mg per day to 50 mg on Day 5. Measures were assessed daily (days 0-7) with 21-day telephone follow-up. Feasibility was measured by the time taken to enrol the sample. Safety was the number of adverse events (AEs) by system organ class. Retention was the proportion to complete treatment. Other measures included the Treatment Satisfaction Questionnaire for Medication (TSQM), the Amphetamine Withdrawal Questionnaire and craving (Visual Analogue Scale). RESULTS: Ten adults seeking inpatient treatment for MA withdrawal (9 male, median age 37.1 years [IQR 31.7-41.9]), diagnosed with MA use disorder were recruited. The trial was open for 126 days; enroling one participant every 12.6 days. Eight of ten participants completed treatment (Day 5). Two participants left treatment early. There were no treatment-related serious adverse events (SAEs). Forty-seven AEs were recorded, 17 (36%) of which were potentially causally related, all graded as mild severity. Acceptability of the study drug by TSQM was rated at 100% at treatment completion. Withdrawal severity and craving reduced through the admission. CONCLUSION: A tapering dose regimen of lisdexamfetamine was safe and feasible for the treatment of acute methamphetamine withdrawal in an inpatient setting.

Trial protocol of an open label pilot study of lisdexamfetamine for the treatment of acute methamphetamine withdrawal.

INTRODUCTION: Methamphetamine (MA) use disorder is an important public health concern. MA withdrawal is often the first step in ceasing or reducing use. There are no evidence-based withdrawal treatments, and no medication is approved for the treatment of MA withdrawal. Lisdexamfetamine (LDX) dimesilate, used in the treatment of attention deficit hyperactivity disorder and binge eating disorder has the potential as an agonist therapy to ameliorate withdrawal symptoms, and improve outcomes for patients. METHODS: A single arm, open-label pilot study to test the safety and feasibility of LDX for the treatment of MA withdrawal. Participants will be inpatients in a drug and alcohol withdrawal unit, and will receive a tapering dose of LDX over five days: 250mg LDX on Day 1, reducing by 50mg per day to 50mg on Day 5. Optional inpatient Days 6 and 7 will allow for participants to transition to ongoing treatment. Participants will be followed-up on Days 14, 21 and 28. All participants will also receive standard inpatient withdrawal care. The primary outcomes are safety (measured by adverse events, changes in vital signs, changes in suicidality and psychosis) and feasibility (the time taken to enrol the sample, proportion of screen / pre-screen failures). Secondary outcomes are acceptability (treatment satisfaction questionnaire, medication adherence, concomitant medications, qualitative interviews), retention to protocol (proportion retained to primary and secondary endpoints), changes in withdrawal symptoms (Amphetamine Withdrawal Questionnaire) and craving for MA (visual analogue scale), and sleep outcomes (continuous actigraphy and daily sleep diary). DISCUSSION: This is the first study to assess lisdexamfetamine for the treatment of acute MA withdrawal. If safe and feasible results will go to informing the development of multi-centre randomised controlled trials to determine the efficacy of the intervention.

Use of COVID-19 testing in the first year of the COVID-19 pandemic among cohorts of people at the intersection of drug use and HIV.

People living with (PLWH) and at risk for HIV and people who use drugs (PWUD) are at heightened risk for health consequences of COVID-19 because of compromised immunity and high comorbidities. We studied their use of COVID-19 testing during the first year of the COVID-19 pandemic. Eight NIDA funded cohorts across North America in the Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) administered multiple waves of a COVID-19 survey. Respondents were at least 18 years of age, half PLWH, and many active substance users. Wave one of the COVID-19 survey was May-November, 2020 and wave two October 2020-April 2021. Associations of COVID-19 testing with demographics, socio-demographics, substance use, and HIV-status were assessed. Of the 3762 responses from 2331 individuals, half reported ever COVID-19 testing (49.1 %), with 4.3 % reporting a positive test (163/3762 surveys=4.3 %) and 41.5 % of people reporting current symptoms reported having been tested. In multivariable analysis adjusting for age, sex, and cohort type associations with COVID-19 testing included African American/Black identification compared to Caucasian/white (adjusted odds ratio (AOR)= 0.68; 95 % confidence interval (CI) 0.53, 0.88); being unemployed (AOR=0.61; 95 % CI 0.51, 0.73), and living with HIV (AOR=0.76; 95 % CI0.65, 0.90). Findings from these C3PNO COVID-19 modules suggests that in the first year of the pandemic COVID-19 testing was not broadly accessed by these marginalized populations including PLWH and those unemployed. Factors associated with not testing may also parallel those for vaccination and identify populations needing better access to COVID-19 prevention.
